ATMOSPHERIC TURBULENCE OBSERVATION AND SIMULATION

Accurate monitoring and understanding of atmospheric turbulence are crucial for improving flight safety and weather prediction. However, traditional observation methods such as aircraft observations are not suitable for Taiwan, which has complex terrain and terrain compression characteristics. Therefore, we made a onboard flight set which combination a Mateksys FC H743-WLite flight controller unit and GPS sensor and Mission planner software to record the 50-Hz onboard flight information to estimate the atmospheric turbulence. This unit was used on a unmanned aerial vehicles (UAVs) and research jets as observation platforms well. UAVs offer flexibility and maneuverability, allowing them to fly at lower altitudes and in specific regions, collecting real-time data with high spatial resolution, including aircraft coordinates, inertial navigation data, flight attitudes, and turbulence indicators such as eddy dissipation rate to identify convective regions. We also used two research jets are Gulfstream-100 (ASTRA, AIDC, Taiwan) and Gulfstrea-400 (G-4, DAS, Japan) for tropical storm dropsonde observation.
